She's understandably been keeping a low profile since photographs emerged which showed her apparently cheating on boyfriend Robert Pattinson with married father-of-two Rupert Sanders.

But on Monday, Kristen Stewart emerged in Los Angeles as she attempted to get her life back on track following the affair with Sanders, who directed her movie Snow White And The Huntsman.

The 22-year-old actress showed the strain of the difficult past few weeks as she displayed her even slimmer frame in a cropped white T-shirt and rolled up skinny jeans.

However, Kristen, perhaps unwittingly, still managed to refer back to her infidelity by teaming her outfit with a Baltimore Orioles cap and a backpack - both of which belong to her estranged boyfriend Robert Pattinson.

She also wore a gold ring which was given to her by Pattinson.

And sources close to the Twilight actor have revealed he is less than impressed with Kristen's outfit choice after seeing the photographs.

A source told RadarOnline.com: 'Rob's not impressed by the photo of Kristen, and he's not sure what she's trying to prove. He's been doing his best to push through this, promoting his movie and everything while still trying to figure out where he and Kristen stand.

'With these photos of her wearing his hat, backpack and ring, it's just got him wondering what kind of mind games she's playing.'

Kristen's outing also came amid claims she has been advised by her mentor Jodie Foster, with whom she starred in movie Panic Room, to show her face in public and not hide away.

While Kristen has been keeping a low profile, Pattinson has been doing the rounds promoting his new movie Cosmopolis.

The 26-year-old actor's latest appearance came on Jimmy Kimmel, when he admitted that he has now moved out of the home he shared with Kristen.
